IMPROVEMENT IN ELECTRO-GALVANIC BANDS.

Specification forming part of Letters Patent No. 156,053, dated October20, 1874; application filed August 10, 1874.

`To all whom it may concern:

of New York, have invented certain Improvements in Electro-VoltaicChain-Belts, of which the following is a specification:

This invention relates to certain new andv useful improvements inelectric belts or bands for imparting a continuous current ofelectricity to dilferent parts of the body for the treatment of variousdiseases; and it consists of a series of alternate plates of copper andzinc, hinged together so as to form a liexible band or chain, the wholebeing inolosed by a covering of leather, or other suitable material. Oneend of said band terminates with a copper plate forming the negativepole of the belt, the other with a zinc plate forming the positive pole.To each end or pole of the belt, is secureda peculiar metallic pad andconductor, and at various points along the inside of the belt conductorsare provided, in order to distribute the electricity at various pointsalong the circuit of the belt to the person of the wearer. The leatherinsulates the plates between the conductors, and, in combination withsaid plates and conductors, forms a series of sm all batteriesthroughout the entire length of the belt, the poles of which communicatewith the person at various points, instead of a continuous battery inwhich the two poles at the end of the belt alone conduct the electricitythrough the body.

The advantage of my form of belt over all others will be apparent,since, by its use the electro-current can be divided up and applied tovarious parts of the body at the Sametime,

lwhile in such belts as heretofore constructed the current could only beapplied at two points -the ends of the belt.

In the drawings, Figure 1 represents a perspective view of my improvedbelt; Fig. 2, a sectional view of one of the metallic pads forming thepoles at the end of the belt. Fig. 3 represents a detached view of thebelt with a portion of the covering removed, showing the copper and zincplate. Fig. 4 represents a sectional view of the sockets or ferrulesatcached to the ends of the belt, to which the metallic pads are hinged.Fig. 5 represents Aa sectional view of the belt, showing the confducting-buttons and method of attaching the same.

A represents the metallic chain which forms the battery, consisting of aseries of alternate plates of' copper and zinc, marked O Z. These platesare hinged together in any convenient manner, and are secured within aleather or other suitable covering, B.

One end of the belt terminates with a zinc plate, forming the positivepole of the battery, and the other with a copper plate, forming thenegative pole. Over each end of the belt is secured a socket, C', bymeans of a screwbolt, l), which passes through the metal plate of thechain, and forms a metallic connection therewith. To the ends of saidsockets are attached the metallic pads E E, which serve to conduct theelectricity from the positive and negative poles to the person. Saidpads are formed of two concavo-convex disks of metal, united with theirconcave sides to gether, forming an easy bearing-surface against thebody. The outer sides of said pads are provided with buttons e e for theband F, by which the belt is secured around the wearer. At variousintervals along the inside of the belt conducting buttons G areprovided. These may be at any convenient distances apart, and shouldconnect alternately with the copper and zinc plates. They may beattached to the plates in any convenient manner, provided a metalliccommunication between said buttons and plates is formed. Fig. 5 shows aconvenient manner of attaching them by means of a metallic shank passingthrough the leather and the metallic plate, where it is fastened.

The belt may be provided with supporting straps or bands, in order tosupport it in various positions upon the body.

It needs no preparation previous to being placed upon the body, as theperspiration of the person, permeating the leather or covering andacting upon the plates, will generate the electricity.

What I claim isl. The combination of the hinged metallic plates ofcopper and zinc with the covering cured over the ends of the belts, andhaving B and conducting-buttons G, for distributing el metallicconnection with the plates forming the electricity to the body atVarious points the chain, as herein described. along the circuit of thebelt, as herein desobe JAMES BRYAN.
